BACKGROUND

In late 1990′s to the early 2000′s, mobile medical workstations (carts)were used to make computers portable so that nurses could document careat the patient bedside instead of transcribing notes. Early (and perhapsthe first) mobile workstation and battery systems were referenced withinU.S. Pat. No. 6,492,220 and U.S. Pat. No. 7,222,031. These patentsreference a basic workstation with a basic rechargeable battery. Themost commercially available battery at that time was a sealed lead acid(SLA), which were relatively inexpensive and mass produced for theautomobile market. The characteristics of the SLA chemistry providegreat ‘cranking power’ to start a car, for example, but does not providea long life when it is discharged over a long period, such as used inmedical facilities. The SLA battery would only provide 6-8 months ofuseful life before it needed to be replaced.

The advancements in battery technology provided opportunities for mobileworkstation power systems to improve efficiency and functionality.Nickel-metal hydride (NiMH) batteries where a good replacement for SLAas they offered longer life and faster charging. By 2010-2013, the costof lithium-ion (Li-Ion) batteries fell to a level that compelled themobile workstation market to adopt Li-Ion chemistry.

Up until 2008, mobile workstation batteries were ‘fixed’ mounted withina housing mounted to the bottom of a workstation. The ‘fixed’ batteryforced the user to take the cart out of service in-order to charge whichcreated a hassle because nurses forget or unwilling to plug-in the cartto recharge the batteries. The number one point of failure withworkstations is the battery because the user fails to plug-in. Downtimedue to ‘dead batteries’ forces hospitals to buy more carts which createsbudget and other problems. In 2008, Stinger Medical, now owned byEnovate medical, developed and patented the first hot swappable batterysystem whereby a removable battery is placed in a holster andcommunicates with a small backup battery at the bottom of the cart toprovide continuous power when the removable battery is removed. The userhas then had two minutes to replace the removable battery with a secondbattery that was charged remotely on a wall charger. This system waspatented in 2008 (U.S. Pat. No. 7,800,255).

However, and even as battery technologies have improved, medical carts(workstations) still generally suffer from inefficient, interrupted,unreliable, and short-lived power delivery. Said power systems also allrely on fans to cool the batteries, noting that the air movement overdirty components, especially within a hospital or other medical setting,could contaminate the air and potentially cause or contribute tohospital acquired infections.

In view of the same, a power system configured to deliver efficient,uninterrupted, and reliable power, using one or more hot swappable longlife batteries that are efficiently charged, without the added risk ofcontaminating a medical environment, would be well received in themarketplace.

For the purposes of promoting an understanding of the principles of thepresent disclosure, reference will now be made to the embodimentsillustrated in the drawings, and specific language will be used todescribe the same. It will nevertheless be understood that no limitationof the scope of this disclosure is thereby intended.

An exemplary power system of the present disclosure is shown in FIG. 1 .As shown therein, an exemplary power system 100 of the presentdisclosure comprises a housing 102 configured to and capable of coupling(attaching) to a workstation and/or other portable and non-portable,mobile, and/or stationary fixtures, including, but not limited to,medical carts as referenced herein. The term workstation 104, as usedherein, refers to said workstations, portable, non-portable, mobile,and/or stationary fixtures. Power systems 100 of the present disclosurecan further comprise one or more mounting structures 106, which may alsobe referred to herein as one or more cradles, whereby said mountingstructure(s) 106 is/are configured to receive one or more energy/powerstorage devices 110, such as batteries, capacitors, and/or fuel cells(all exemplary energy/power storage devices 110). As such, exemplarypower systems 100 of the present disclosure can comprise one or moreenergy/power storage devices 110.

Power systems 100 of the present disclosure further comprise electroniccircuitry 120 configured to facilitate communication of battery status,state of charge, and/or overall battery health. Said electroniccircuitry can comprise, or be coupled to, an electrical connector 122configured to electrically connect/couple to one or more energy/powerstorage devices 110 of the present disclosure. Said connectors 122,along with circuitry 120, allow batteries (energy/power storage devices110) to charge and/or discharge as desired/instructed.

Housings 102 of the present disclosure can further comprise, or beelectrically connected/coupled to, a power supply 130 (such as acharger, for example) having its own charge circuitry 132 (or coupled tosaid charge circuitry 132). Power supplies 130 of the present disclosureare configured to receive input power from a power cord 134 (alsoreferred to herein as a line-cord) connected to an alternating current(AC) or direct current (DC) power source 150, and/or configured toreceive input power from an external AC or DC power source 150 viainduction charging.

Circuitry 120 and/or charge circuitry 132 of the present disclosure canbe configured to communicate state of charge, battery health and othersystem related data from said energy/power storage devices 110,communicate and/or control output of said energy/power storage devices110, and/or prioritize charge or discharge of energy/power storagedevices 110.

Exemplary power systems 100 of the present disclosure may furthercomprise one or more backup energy storage devices 175, such as one ormore other energy/power storage devices 110, whereby said backup energystorage devices 175 are positioned within and/or coupled to housing 102and are configured to allow for continuity of power in the absence ofenergy/power storage devices 110 and/or an external AC or DC powersource 150. For example, power systems 100 of the present disclosure canbe configured to deliver power to a workstation 104 a) by way of a powercord 134 connected to an external AC or DC power source 150, b) by wayof induction charging of one or more energy/power storage devices 110using an external AC or DC power source 150, c) by way of one or moreenergy/power storage devices 110, d) by way of one or more backup energystorage devices 175, or e) using a combination of any of a), b), c),and/or d).

In view of the foregoing, circuitry 120 and/or charge circuitry 132 ofthe present disclosure can be configured to recognize the absence of abattery or batteries (absence of energy/power storage devices 110),depleted power levels of the same, and/or the absence of an external ACor DC power source 150, and to communicate said condition to allow powerfrom internal backup battery (backup energy storage devices 175) toprovide output power to workstation 104 equipment requiring continuityof power.

Output power voltage(s), from energy/power storage devices 110, externalAC or DC power sources 150, and/or backup energy storage devices 175,can be programmable so to match the required voltage(s) of theworkstations 104 being powered. Circuitry 120 and/or charge circuitry132 of the present disclosure may comprise an internal and/or externalinverter 140 to match local power and mechanical mating plugrequirements.

In various embodiments of power systems 100 of the present disclosure,data from said power systems 100, including, but not limited to, battery(energy/power storage devices 110 and/or backup energy storage devices175) condition, health, system temperature and/or other parameters canbe communicated to an external devices/interfaces 200, such as a desktopcomputer, laptop computer, smartphone, personal digital assistant (PDA),tablet, or other electronic device, which may be separate from, orcomprise part of, a workstation 104. In various embodiments, variousgraphical user interface (GUI) elements may be used, including, but notlimited to, one or more graphics, emoji, scales, clocks, etc.(collectively GUI elements 310), such as shown in FIG. 3 , and/or othermethods of communicating power system 100 information, including stateof battery charge. Said GUI elements 310 can be displayed on a screen308 of an external device/interface 200, for example, such as shown inFIG. 3 .

The present disclosure also includes disclosure of methods for providingelectrical power to a computer, monitor(s), scanners, printers, motors,actuators and other equipment requiring power (exemplary externaldevices/interfaces 200, which may comprise or be separate fromworkstation(s) 104) from a power system to perform its intendedfunction. In at least one embodiment of said method, the methodcomprises the step of programming the internal power supply 130 toperform a desired/proper charge algorithm or charge protocol as toensure safety and longevity of the energy/power storage devices 110charged using said power supply is maximized. In at least one embodimentof said method, the method comprises the step of programming theinternal power supply 130 to manage the state of charge of the one ormore energy/power storage devices 110 mounted or fixed to the powersystem 100 in order to match the user’s desired workflow requirements orto generally match the power needs of the external devices/interfaces200 receiving power therefrom.

It is well understood that the use of cooling fans within an operationalenvironment of a power system 100 is not ideal as such a cooling fan isa point of failure, collecting airborne substances such as dust anddirt, and may present an infection control hazard within a hospitalenvironment. It is understood that the cooling fan is a requirement ofpower systems currently on the market to control the system temperatureto prevent safety hazard and/or to pass the thermal requirements ofagencies that test/certify power systems for use.

However, the present disclosure includes disclosure of power systemsthat eliminate the need/use of a cooling fan or other objects or devicesintended to move air for the purposes of cooling power system 100components that produce and/or are effected by heat while operatingwithin the thermal tolerances outlined in certifying agencyrequirements, such as, but not limited to, IEC 60601-1

Power system 100 architecture and design is a critical component inenabling fanless charging. To accomplish the same, internal heatsinks250, in thermal communication with one or more components of powersystems 100 of the present disclosure, are used, which are configured totransfer heat from said power system components. Heat sinks 250 can thentransfer heat to an external case 275 surrounding at least part ofhousing 102, as desired/necessary. Proprietary high efficiency AC/DC,DC/DC and power switching systems are therefore incorporated withinpower systems 100 to help reduce system heat. Said power switchingsystems can comprise or be portions of energy/power storage devices 110,electronic circuitry 120, electrical connectors 122, power supplies 130,charge circuitry 132, internal and/or external inverter, and/or backupenergy storage device 175.

Firmware (software) is also an important component in charging since itcan be used to monitor the temperature of the power system 100 and/orcomponents thereof and reduce the charge current, for example, iftemperature reaches defined set points. Said firmware (software 302) canbe stored within a storage medium 304 (such as flash memory, a harddrive, etc., configured to store software 302) and use a definedtemperature/current profile for the power system 100, so to maintaintemperatures within a desired range while providing power from powersystem 100 as required/desired within said temperature range. Hysteresiscan be used and implemented within exemplary power systems 100 toprevent constant power adjustment time and temperature. A processor 300(such a microprocessor), in communication with storage medium 304, canoperate based upon instructions from software 302, to accomplish thevarious charging, power delivery, temperature regulation, andinformation/data communication as referenced herein.

Delivery of power from power systems 100 of the present disclosure toworkstations 104 and/or other external devices/interfaces can bemaximized, whereby the power is determined by AC/DC utilized, theelectronic circuitry 120 or charge circuitry 132 (such as copper) upon aprinted circuit board (PCB) 280, as shown in FIG. 2 , along with theenergy/power storage devices 110 themselves. Components of power system100, such as power supply 130, charge circuitry 132, internal and/orexternal inverter 140, etc., can be configured to communicate withenergy/power storage devices 110 via serial communication to ensureovercharge of said energy/power storage devices 110 does not occur. Inaddition, exemplary power systems 100 of the present disclosure, asreferenced herein, can monitor temperature and voltage levels to ensureproper cutoff occurs of the power charging the energy/power storagedevices 110, such as by way of power supply 130. Current can be reducedbased upon voltage of energy/power storage devices 110, if needed, foroptimal charging and power delivery. Cell chemistry and energy/powerstorage devices 110 configuration and assembly are also important toensure maximum charge current. For example, if the individual orcollective energy/power storage devices 110 or cells thereof cannothandle a set 20A (or higher or lower) charge rate, for example, then thepower system 100 will use the maximum rate possible that is communicatedto the power system 100 from the energy/power storage devices 110themselves via serial communication. For example, an A123 battery packis capable of only 12.5A rate, so it would regulate charging to 12.5Ainstead of 20A, in the aforementioned example, as desired/required.

Regarding variable DC output, exemplary power systems 100 of the presentdisclosure, as referenced herein, can utilize digital potentiometers 400controlled by a microprocessor (processor 300) to adjust a feedbackcontrol circuit (electric circuit 120 and/or charge circuit 132) in theDC buck/boost circuits. Exemplary power systems 100 allow for end userconfiguration of the DC output based upon using a SW utility to setlimits, or can be set via power system 100 configuration duringworkstation 104 assembly. The DC output voltage levels can monitordifferent power system 100 parameters to adjust the DC output level,with said parameters including, for example, AC power connected, DCoverload condition, and DC current output. FW can monitor the parametersand adjust the voltage output via the buck/boost control circuits.

Exemplary power systems 100 of the present disclosure can implement amultivariate analysis including, but not limited to, a combination ofcell chemistry, voltage, current, temperature, user runtimerequirements, and the like, to determine which multi-rate charge routineis utilized to return said battery packs (energy/power storage devices110) to a 100% state of charge, ensuring safety and utility aremaximized.

Multi-rate charging, within the scope of the present disclosure, can bedescribed as follows. Constant voltage (CV) type charging can be used,for example, with various low power systems, medical systems, andindustrial systems. A corresponding charge algorithm can operateindependently from the state of charge. At the connection of theenergy/power storage device 110, for example, a charger output voltagecan be set (such as setting an output voltage of a power supply 130 ofthe present disclosure), and power system 100 can charge theenergy/power storage device 110 at a constant rate until the voltage ofthe energy/power storage device 110 equals the set charger outputvoltage. As the voltage differential between the charger and theenergy/power storage device 110 reduces, charge current reduces, and thecharge can terminate after, for example, the charge current is less thana charge termination setpoint for a specified charge termination time.Temperature of power system 100 and/or temperature of energy/powerstorage device 110 can impact charge current (such as for safety), suchas when the energy/power storage device 110 temperature exceeds amaximum temperature setpoint, the charge can be terminated. When thecharging system temperature exceeds a high temperature setpoint, forexample, the charge current is or can be reduced to allow power system100 and/or energy/power storage device 110 to cool and safely operate.When the charging system exceeds a maximum setpoint, the charge can beterminated to prevent damage to the power system 100 and/or theenergy/power storage device 110, also such as for safety. As the chargervoltage and the battery pack (energy/power storage device 110)differential is reduced over time, the charge current can slowly reduceover time as well when this multi-step charging mechanism is used.

Such an exemplary charging procedure differs from step charging, forexample, whereby a system charging current is set at the beginning of acharge and such that the battery charges until a predetermined state ofcharge (such as 60% to 80%) or voltage is reached, and once thatsetpoint is reached, the current is “stepped down” to allow the batteryto charge at a lower rate, with the current step and number of stepstypically determined by software within the charging device.

Energy/power storage devices 110 of the present disclosure are hotswappable, meaning that while power system 100 is used to deliver powerto a workstation 104, for example, one or more energy/power storagedevices 110 can be removed from power system 110 and, if desired,replaced with a replacement energy/power storage device 110. Forexample, various embodiments of power systems 100 of the presentdisclosure can incorporate one, two, three, four, or more energy/powerstorage devices 110 therein. In embodiments having one energy/powerstorage device 110, it can be removed while power system 100 isdelivering power, as backup energy storage device 175 can be used todeliver power during the replacement of said energy/power storage device110. In power system 100 embodiments having two or more energy/powerstorage devices 110, one or more energy/power storage device 110 can beremoved while power system 100 is delivering power, with said powerdelivered from any remaining energy/power storage devices 110 and/orbackup energy storage device 175. While power system 100 is plugged intoAC or DC power source 150, or otherwise in a mode for charging using ACor DC power source 150 (such as by induction charging), energy/powerstorage devices 110 and/or backup energy storage device 175 can becharged using AC or DC power source 150, while delivering power to aworkstation 104, for example, as may be desired.

Power systems 100 of the present disclosure are novel over existingpower systems in the marketplace as they a) can be hot swappable, anoted above, b) can use a unique method of charging, as noted herein, c)can use programmable DC outputs, as referenced herein, and d) canoperate as desired, namely to deliver a desired amount of power within adesired temperature range, without the use of a fan or other aircirculating element.

As referenced herein, the present disclosure also includes disclosure ofa workstation 104 having a power system 100 of the present disclosure,whereby the power system 100 is configured to provide power toworkstation 104, such as, for example, to power a computer, monitor(s),scanners, printers, motors, actuators and other equipment requiringpower (exemplary external devices/interfaces 200, which may comprise orbe separate from workstation(s) 104, as referenced herein) to performits intended function(s).
